Why does my hot water keep going cold then hot?
Combi boilers are a lot more reliable than they were ten years ago. However, combi boilers are prone to the common problem of causing the hot water to go cold or lukewarm and then back to hot again. Symptoms like these are usually signs of a blockage in the hot water heat exchanger in the boiler.
Why is my hot water running while my cold water is running?
One day, after using the shower, we noticed the cold taps were running lukewarm water from every faucet–a problem I would come to learn is called “hot-cold crossover”. This wasn’t some simple, obvious leak, either–this one would take some detective work. Time to call a plumber, some would say.
Why is hot water coming out of my Cold Faucet?
This could cause water to be overheated and flow into the cold water pipes. Copper is highly heat conductive, which means heat passes through it very easily. If you’re running hot water in the faucet and have copper pipes, the plumbing could heat up the entire faucet for a period of time.
Is it normal for hot water lines to run parallel to cold water lines?
Plumbing often needs to fit in tight places. So, it’s normal for hot and cold water lines to run parallel and close to each other on the way to the faucet. However, if they’re too close, the heat of the hot water pipe could be affecting the cold water line.
What can I do about hot water coming out of cold taps?
If the cold water intake line is comprised of PVC or similar plastic pipe, either directly from the heater or above the initial copper pipe, you can also make an “improvised” heat trap by incorporating a 6-12″ vertical drop in the line. Recall that the problem is convection–hot water’s tendency to rise upward.

Why does my tap water get warmer when I let it run?
Water from the cold tap getting warmer instead of cooler if you let it run seems odd, unless your cold water pipes are in contact with hot water pipes, or unless you have a long run of pipe, either under your own property or from the city, that is buried too shallow and picking up heat from the ground, heated by the sun.
What happens if you let water run for a minute or two?
If you let the water run for a minute or two, does it become cool again? Cold water pipes do tend to settle at room (or wall) temperature since they generally aren’t insulated, and it can take a little while for the water running through them to cool them down again. – keshlam Sep 14 ’14 at 21:43
Why does my house run out of hot water so fast?
This tends to happen when the number of people showering at the same time increases. Of course, this leaves the last person exposed to running out of hot water fast. Taking long showers also causes you to run out of water supply sooner than expected. Furthermore, hot water runs out when running various machines in the house at the same time.
